Description

[0001] This application claims the priority of Chinese patent application No. 2023110348829 filed on August 16, 2023. This application cites the entire text of the above patent application. Technical Field

[0002] The present disclosure relates to the technical field of instant hot water dispensers, and in particular to a heating device and an instant hot water dispenser. Background Art

[0003] The current instant hot water dispenser uses a quick heating element to quickly heat water. The quick heating element converts electrical energy into thermal energy, which is then transferred to the water. The powerful heat is used to quickly heat the water and obtain hot water. Due to the high power and power density of the quick heating element, the water quickly heats up when it contacts the heating structure inside the quick heating element, generating a large amount of water vapor. Therefore, steam is easily sprayed when high-temperature water is discharged, posing a safety hazard.

[0004] In view of the above problems, the current solutions adopted by the rapid heating body are to lower the maximum temperature setting of the rapid heating body or to increase the water vapor separation structure in the subsequent process. The rapid heating bodies adopting these two solutions lack availability and usability. Utility Model Content

[0009] A vortex spoiler is provided at the first position of the heating body tube, and the vortex spoiler is used to disturb the water flow entering the interlayer so that the water flow entering the interlayer is in a swirling state. The first position is adjacent to the end where the water inlet of the shell is located.

[0010] In a further embodiment, the outer shell is cylindrical, and the water inlet and the water outlet are respectively arranged at two ends of the outer shell.

[0011] In a further embodiment, a vortex spoiler is provided at a second position of the heating body tube, and the vortex spoiler is used to disturb the water flow at the water outlet so that the water flow temperature at the water outlet is uniform, and the second position is adjacent to the end of the water outlet of the shell.

[0012] In a further embodiment, sealing rings are provided on the water inlet and the water outlet, and a temperature sensor is also provided on the water outlet, and the temperature sensor is used to detect the actual outlet water temperature.

[0013] In addition, the present disclosure also proposes a water treatment device, which uses the above-mentioned rapid heating body to heat water.

[0014] In a further embodiment, the water treatment device comprises a temperature setting control, and a maximum value of a temperature setting range of the temperature setting control is less than or equal to 100°C.

[0015] In a further embodiment, the water treatment device further includes a target water outlet, and the target water outlet is used to directly discharge the water heated by the rapid heating body.

[0016] In addition, the present disclosure also proposes a water treatment method, which is applied to the above-mentioned water treatment device, comprising:

[0017] Heating the water in the water treatment device based on the rapid heating body in the water treatment device to obtain heated water;

[0018] When the target water outlet of the water treatment device is opened, the heated water is directly discharged.

[0019] In a further embodiment, the step of heating the water in the water treatment device based on the rapid heating body in the water treatment device to obtain heated water includes:

[0020] Open the water inlet of the quick-heating heater, so that water flows into the interior of the quick-heating heater from the water inlet of the quick-heating heater, passes through the vortex spoiler of the quick-heating heater, flows along the heat-conducting fluid of the quick-heating heater, and then flows in a rotating manner around the heating body tube of the quick-heating heater to the water outlet of the quick-heating heater to obtain the heated water.

[0021] In a further embodiment, the water flow is disturbed to form turbulence when passing through the vortex spoiler of the rapid heating body, and enters the interior of the rapid heating body in the turbulent flow.

[0022] A heating device, comprising:

[0023] Draft tube;

[0024] A heating tube, the heating tube is sleeved outside the flow guide tube and forms a channel between the heating tube and the flow guide tube; the inner wall of the heating tube constitutes a heating body;

[0025] A guide ring is disposed between the guide tube and the heating tube and divides the channel into a spiral heating channel;

[0026] The guide ring is made of a heat-conducting material, and at least a portion of the guide ring is in contact with the heating body to form a heat-conducting path;

[0027] The length of the heating channel is L1, the length of the heating body is L2, and the ratio of L1 to L2 is in the range of 5-10.

[0028] In this solution, the heating device reduces the internal volume of the heating device by setting a spiral guide ring in the interlayer between the heating tube and the guide tube, thereby reducing the water flow entering the heating device and increasing the heating speed of the water; and the spiral heating channel causes the water to flow in a spiral in the heating channel to form a self-spinning water ring, which prevents the water from flowing in a straight line, increases the contact opportunities between water in different parts and the heating body, speeds up heat conduction, balances the temperature of the heating body, avoids the existence of local high-temperature heating points in the heating body, prolongs the life of the heating body, and prevents the water from being vaporized, thereby preventing steam from being generated. At the same time, the self-spinning water ring also speeds up the heat exchange between water, heats up quickly, and has small fluctuations in water temperature. The spiral heating channel extends the heating path, heats quickly, and has a uniform water temperature.

[0029] In addition, since the guide ring is made of a heat-conducting material and is in contact with the heating body, the heating tube can conduct heat through the spiral guide ring, increasing the contact area between the heating body and the water, so that the water heats up quickly. The guide tube and the guide ring are arranged in the heating tube, so that the volume of the heating channel of the interlayer is small, so that the heating device expands with heat and contracts with cold, and when the heating is stopped, the amount of heat overflowing water is small.

[0030] Furthermore, the ratio of the length of the heating channel to the length of the heating body is set to 5 to 10, which can extend the heating path and improve the heating effect on the heating body per unit length. Preferably, the ratio of L1 to L2 is in the range of 6 to 8.

[0031] Preferably, the heating device further comprises a shell, a water inlet unit and a water outlet unit, the heating tube is arranged in the shell, the water inlet unit cooperates with the water inlet end of the heating channel, and the water outlet unit cooperates with the water outlet end of the heating channel.

[0032] In this solution, the housing is used for heat preservation to prevent the heat loss of the heating pipe, and the housing is also used to protect the heating pipe. The water inlet unit has a water inlet, which is used to connect tap water or purified water. Water flows into the heating pipe through the water inlet of the water inlet unit, and the water flows out from the water outlet of the water outlet unit after being heated by the heating pipe, and the user obtains the required hot water at the water outlet.

[0033] Preferably, the heating tube is vertically arranged, the water inlet unit is located at the upper end of the heating tube, and the water outlet unit is located at the lower end of the heating tube.

[0034] In the present solution, the above-mentioned structural setting is adopted to form water inlet at the lower end and water outlet at the upper end, that is, water outlet in an overflow manner. The water is heated while spirally rising in the heating channel. The same part of water can contact different parts of the heating body. The water heats up quickly and evenly, and the heating channel is always filled with water, preventing the heating body from having local high-temperature heating points and extending the life of the heating tube.

[0035] Preferably, the water inlet unit includes a lower shell having a water inlet cavity, a first diverter is provided at the water inlet end of the heating channel, a plurality of blades are provided on the first diverter, a diverter channel is formed between adjacent blades, and the diverter channel is respectively connected to the water inlet cavity and the heating channel.

[0036] In this solution, the first diverter diverts the water through the blades and disturbs the water to form a self-spinning water ring, preventing the water from flowing in a straight line, so that the water is disturbed before entering the heating tube, increasing the contact opportunities between different parts of the water and the heating body, accelerating heat conduction, balancing the temperature of the heating body, avoiding the existence of local high-temperature heating points in the heating body, preventing the water from being vaporized, extending the life of the heating body, and also accelerating the heat exchange between the water, with small fluctuations in water temperature. The water can move along the spiral heating channel, extending the heating path, heating quickly and with uniform water temperature.

[0037] Preferably, the blades are arranged to be inclined, and the inclination direction of the blades is consistent with the rotation direction of the heating channel.

[0038] In this scheme, the above-mentioned structural setting is adopted to form spinning water, which increases the contact opportunities between different water and the heating body, accelerates heat conduction, and improves the water turbulence effect. At the same time, the spinning water also accelerates heat exchange between water, and the temperature rises quickly and evenly. Moreover, the spinning water has fast heat conduction, balances the temperature of the heating body, and avoids local high temperature burning the heating body.

[0039] Preferably, the blades are arranged to be inclined, and the inclination direction of the blades is opposite to the rotation direction of the heating channel.

[0040] In this solution, the above-mentioned structural arrangement is adopted to improve the water disturbance effect.

[0041] Preferably, the water outlet unit includes an upper shell having a water outlet cavity, a second diverter is provided at the water outlet end of the heating channel, a plurality of blades are provided on the second diverter, a diverter channel is formed between adjacent blades, and the diverter channel is respectively connected to the water outlet cavity and the heating channel.

[0042] In this solution, the second diverter disturbs the heated high-temperature water so that the water can be quickly mixed and the water temperature at the water outlet is balanced.

[0043] Preferably, the blades are arranged to be inclined, and the inclination direction of the blades is opposite to the rotation direction of the heating channel.

[0044] In this solution, the above-mentioned structural arrangement is adopted to enable water to flow out smoothly and reduce water resistance.

[0045] Preferably, the blades are arranged to be inclined, and the inclination direction of the blades is the same as the rotation direction of the heating channel.

[0046] In this solution, the above-mentioned structural setting is adopted to improve the mixing effect of water and balance the water temperature at the water outlet.

[0047] Preferably, the cross-section of the heating channel along the axial direction of the heating tube has a first size segment and a second size segment, the first size segment is arranged close to the heating tube, the second size segment is located in the middle of the cross-section, and the length of the first size segment is greater than the length of the second size segment.

[0048] In this solution, the above-mentioned structural setting is adopted to form a narrow structure in the middle and an open structure at the end. The open structure corresponds to the heating body setting, and the water flow rate is large, so that a larger heating body can heat the water and improve the heating efficiency. The narrow structure is far away from the heating body, so its water flow rate is small, so as to achieve balanced heating.

[0049] Preferably, the guide ring is made of a heat-conducting material, and the cross-section of the heating channel along the axial direction of the heating tube presents a regular pattern, and the regular pattern includes a first straight line segment, a first arc segment, a second straight line segment, and a second arc segment connected end to end in sequence, the first straight line segment and the second straight line segment are arranged opposite to each other, the first arc segment and the second arc segment are arranged opposite to each other, and the first arc segment and the second arc segment protrude in a direction approaching each other.

[0050] In this solution, since the guide ring is made of heat-conducting material, the heat of the heating tube can be transferred to the water in the heating channel through the guide ring, so that the first straight line segment, the first arc segment and the second arc segment can heat the water at the same time, thereby increasing the heating area and improving the heating efficiency.

[0051] Preferably, forces are applied to the guide ring at both ends of the heating tube in the axial direction to maintain elastic potential energy.

[0052] In this solution, the guide ring can be compressed by the water inlet unit and the water outlet unit to keep the guide ring elastic potential energy. On the one hand, the guide ring is fixed, and on the other hand, the gap between adjacent spirals is kept fixed to prevent the shape of the heating channel from changing and affecting the heating effect.

[0053] An instant hot water dispenser comprises the heating device as described above.

[0054] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

[0055] The implementation of this disclosure has the following beneficial effects:

[0056] By adding a heat-conducting fluid inside the quick-heating heating body, the volume inside the quick-heating heating body becomes smaller and the heat-conducting area becomes larger, so the water flow entering the quick-heating heating body becomes less, which increases the speed of heating water. The use of the heat-conducting fluid can also increase the contact amount between different water and the heating body tube. A vortex spoiler is also provided at the water inlet of the quick-heating heating body to make the water flow entering the quick-heating heating body in a swirl state, so that the heated water temperature is uniform and no water vapor is formed. The high-temperature water heated by the quick-heating heating body can be directly discharged without generating steam spray. Therefore, the implementation of the present disclosure solves the problem of steam spray when the quick-heating heating body discharges high-temperature water, can improve the speed and maximum temperature setting of the quick-heating heating body heating water, and does not need to subsequently add a water vapor separation structure, and can directly discharge the heated high-temperature water, thereby enhancing the availability and usability of the quick-heating heating body.

[0057] The heating device reduces the internal volume of the heating device by setting a spiral guide ring in the interlayer between the heating tube and the guide tube, thereby reducing the water flow entering the heating device and increasing the heating speed of the water; and the spiral heating channel causes the water to flow in a spiral in the heating channel to form a self-spinning water ring, preventing the water from flowing in a straight line, increasing the contact opportunities between water in different parts and the heating body, accelerating heat conduction, balancing the temperature of the heating body, avoiding the existence of local high-temperature heating points in the heating body, extending the life of the heating body, and preventing the water from being vaporized, thereby not generating steam jets. At the same time, the self-spinning water ring also accelerates the heat exchange between water, heats up quickly, and has small fluctuations in water temperature. The spiral heating channel extends the heating path, heats quickly, and has a uniform water temperature.

[0058] In addition, since the guide ring is made of a heat-conducting material and is in contact with the heating body, the heating tube can conduct heat through the spiral guide ring, increasing the contact area between the heating body and the water, so that the water heats up quickly. The guide tube and the guide ring are arranged in the heating tube, so that the volume of the heating channel of the interlayer is small, so that the heating device expands with heat and contracts with cold, and when the heating is stopped, the amount of heat overflowing water is small.

[0059] Further features and aspects of the present disclosure will become apparent from the following detailed description of exemplary embodiments with reference to the attached drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0076] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0077] Example 1

[0078] Please refer to the instruction manual Figure 1 , which shows a longitudinal cross-sectional schematic diagram of a rapid heating body provided by an embodiment of the present disclosure, such as Figure 1 As shown, the rapid heating body comprises:

[0079] A housing 1, wherein the housing 1 comprises a water inlet 11 and a water outlet 12;

[0080] A heating tube 2, wherein the heating tube 2 is arranged inside the outer shell 1, and a sandwich is formed between the outer shell 1 and the heating tube 2 for water to flow through;

[0081] The heat-conducting fluid 3 is arranged in the interlayer to reduce the volume of the interlayer, so that less water enters the interlayer, thereby increasing the speed of heating water. The heat-conducting fluid 3 is axially fitted and wrapped around the outside of the heating body tube 2, so that the heat-conducting fluid 3 conducts the heat generated by the heating body tube 2 to the water flow in the interlayer, and guides the water flow to rotate around the heating body tube 2 to the water outlet 12. The rotating flow of the water flow helps to increase the contact amount between different water and the heating body tube 2, avoiding the same part of water being in contact with the heating body tube 2 and being continuously heated, thereby forming a positive feedback of water vapor and causing a steam spray problem when high-temperature water is discharged;

[0082] like Figure 2 As shown, a vortex spoiler 4 is provided at the first position of the heating body tube 2, and the vortex spoiler 4 is used to disturb the water flow entering the interlayer so that the water flow entering the interlayer is in a vortex state. The first position is adjacent to the end where the water inlet 11 of the outer shell 1 is located. In the embodiment of the present disclosure, a turbine is selected as the vortex spoiler 4, and the turbine is fixed at the first position on the heating body tube 2. When the water flow passes through the turbine, it is disturbed and forms a vortex, so that the heated water temperature is more uniform and it is not easy to generate water vapor.

[0083] In the embodiment of the present disclosure, a stainless steel spring is selected as the heat-conducting fluid 3. Since the water that does not contact the heating body tube 2 needs heat conduction between the water flow, the heating speed is slow and the heated water temperature is uneven. The heat generated by the heating body tube 2 can be conducted to the water flow faster through the stainless steel spring and the heating body tube 2, so that the water heating speed is faster. The heat-conducting fluid 3 can also be other heat-conducting materials such as copper, aluminum, and zinc. After the water flow enters the quick-heating heating body, it flows along the stainless steel spring around the heating body tube 2 to form a rotating state and flows to the water outlet of the quick-heating heating body. The water flow rotates around the heating body tube 2 to increase the contact amount between different water and the heating body tube and the stainless steel spring, so that more water in the water flow can be heated, the water temperature is more uniform, and the problem of water that has been in contact with the heating body tube 2 being continuously heated to produce water vapor and then causing steam spray is avoided. It should be noted that, in addition to the spring, the heat-conducting fluid can be any other shape that can guide the water flow to rotate around the heating body tube. Therefore, the embodiment of the present disclosure does not limit the material and shape of the heat-conducting fluid 3.

[0084] In a preferred disclosed embodiment, the housing 1 can be made of high-quality aluminum material and die-cast into a cylindrical shape, and the housing 1 can ensure uniform heat distribution. The housing 1 is provided with a water inlet 11 at the bottom and a water outlet 12 at the top, and water flows into the rapid heating body from the water inlet 11 at the bottom, and directly discharges water from the water outlet 12 at the top after heating is completed.

[0085] In the embodiment of the present disclosure, a turbine is also provided at the second position of the heating body tube 2. When the water flow passes through the turbine, it is disturbed, so that the water flow temperature at the water outlet 12 is uniform. At this time, the water temperature at the water outlet is closest to the actual water temperature obtained after heating by the rapid heating body. The second position is adjacent to the end where the water outlet 12 of the outer shell 1 is located.

[0086] The water inlet 11 and the water outlet 12 in the embodiment of the present disclosure are provided with sealing rings, and the water outlet 12 is also provided with a temperature sensor. In order to reduce costs, the temperature sensor can be an NTC temperature sensor. The temperature sensor is connected to an external temperature control device to monitor the water temperature at the water outlet 12 during the operation of the rapid heating body. When the water temperature reaches the preset required temperature, the external temperature control device controls the rapid heating body to stop heating. Since a turbine is provided at the water outlet 12, the detected water temperature is closer to the actual water temperature, so that the temperature sensor can detect the water outlet temperature more accurately, and thus the accuracy of temperature control of the rapid heating body of the embodiment of the present disclosure is also improved.

[0087] Figure 3 The schematic diagram of the structure of the water treatment device according to the embodiment of the present disclosure is shown in FIG. Figure 3The water treatment device specifically includes a rapid heating body 101, a temperature setting control 102 and a target water outlet 103, wherein:

[0088] The rapid heating body 101 is used to heat the water;

[0089] A temperature setting control 102 is used to set the temperature of the hot water required;

[0090] The target water outlet 103 is used to directly discharge the water heated by the rapid heating body.

[0091] Among them, the rapid heating body 101 is the rapid heating body provided in the embodiment of the present disclosure, and the rapid heating body will not cause steam spraying problems when discharging high-temperature water.

[0092] In the embodiment of the present disclosure, the temperature setting control 102 receives the water outlet temperature detected by the temperature sensor of the quick heating body 101, and controls the quick heating body to stop heating when the water outlet temperature reaches the preset required temperature. Specifically, since the quick heating body provided by the embodiment of the present disclosure is used for heating, the water temperature is uniform during heating and no water vapor is generated, and there is no risk of steam spraying when high-temperature water is discharged, so the quick heating body 101 can be heated to obtain 100°C water, and the maximum temperature controlled by the temperature setting control for the quick heating body 101 to be heated can be set to 100°C, that is, the quick heating body provided by the embodiment of the present disclosure improves the maximum temperature setting of the quick heating body.

[0093] Furthermore, since the water temperature is uniform during heating and no water vapor is generated, there is no need to set up a water vapor separation structure to separate the water vapor before discharging the water. The target water outlet can directly discharge the water heated by the rapid heating body.

[0094] Figure 4 A flow chart of a water treatment method according to an embodiment of the present disclosure is shown. The water treatment method is applied to the water treatment device according to the embodiment of the present disclosure, and specifically includes steps S21-S24, as shown below:

[0095] S21 opens the water inlet of the rapid heating body so that water flows into the interior of the rapid heating body from the water inlet of the rapid heating body.

[0096] S22 disturbs the water flow to form turbulence, and the water flow enters the interior of the rapid heating body in the turbulent flow.

[0097] In the disclosed embodiment, a turbine is provided at the water inlet of the rapid heating body in the water treatment device. The water flow is disturbed to form turbulence when passing through the turbine, and enters the interior of the rapid heating body in turbulent flow. The turbulent state can increase the contact amount between different water and the heating body tube 2 and the heat-conducting body 3, so that a large amount of water can be heated. Therefore, the temperature rises more evenly during the heating process and it is not easy to generate water vapor.

[0098] S23 causes the water flow to flow in a rotating shape around the heating body tube to the water outlet;

[0099] In the disclosed embodiment, a stainless steel spring is provided inside the quick-heating heating body in the water treatment device. After the water flows into the quick-heating heating body, it flows along the stainless steel spring in a rotational manner around the heating body tube of the quick-heating heating body to the water outlet of the quick-heating heating body to obtain heated water. Since the water flows around the heating body tube of the quick-heating heating body in a rotational manner, the problem that part of the water flows in contact with the heating body tube of the quick-heating heating body all the time and is continuously heated to generate water vapor is avoided. The contact amount between the water flow and the heating body tube of the quick-heating heating body is increased by rotation, so that the water flow is heated evenly, and the formation of positive feedback of water vapor to cause steam spraying is avoided. Therefore, the heated water can reach a very high temperature, and there is no need to lower the maximum temperature of the quick-heating heating body. The current quick-heating heating body will generate water vapor and cause steam spraying when the outlet water temperature is too high. Therefore, the maximum heating temperature of the current quick-heating heating body cannot be too high, and can usually only reach 85°C.

[0100] S24 discharges the treated water;

[0101] When the target water outlet of the water treatment device is opened, the heated water is directly discharged. Since the rapid heating body of the water treatment device is provided with a heat-conducting fluid and a turbine, a large amount of water can be evenly heated during the heating process without a huge temperature difference, and thus no water vapor will be generated. Even if the water temperature reaches the highest temperature of the rapid heating body, no water vapor will be ejected from the target water outlet along with the high-temperature water to cause a safety hazard, and water can be directly discharged. Therefore, the rapid heating body does not need to add a subsequent water vapor separation structure, which is obviously different from the current rapid heating body that subsequently adds a water vapor separation structure to avoid the problem of steam spraying when discharging high-temperature water.

[0102] Example 2

[0103] This embodiment is basically the same as embodiment 1, except that:

[0104] like Figure 5-Figure 8As shown, this embodiment discloses a heating device, which includes a guide tube 201, a heating tube 202 and a guide ring 203. The heating tube 202 is sleeved outside the guide tube 201, and a channel is formed between the heating tube 202 and the guide tube 201. The inner wall of the heating tube 202 constitutes a heating body. The guide ring 203 is arranged between the guide tube 201 and the heating tube 202, and the channel is divided into a spiral heating channel 100. The guide ring 203 is made of a heat-conducting material, and at least a part of the guide ring 203 is in contact with the heating body to form a heat conduction path. The length of the heating channel 100 is L1, the length of the heating body is L2, and the ratio of L1 to L2 is in the range of 5 to 10. When it meets this range, a longer heating channel 100 can be provided to increase the residence time of the water flow in the heating channel 100, and more heat conduction area can be provided through the guide ring 203 to improve the heating efficiency.

[0105] like Figure 5-Figure 7 As shown, in this embodiment, the heating device reduces the volume inside the heating device by setting a spiral guide ring 203 in the interlayer between the heating tube 202 and the guide tube 201, thereby reducing the water flow entering the heating device and increasing the heating speed of the water; and the spiral heating channel 100 causes the water to flow in a spiral in the heating channel 100, forming a self-spinning water ring, preventing the water from flowing in a straight line, increasing the contact opportunities between the water in different parts and the heating body, accelerating heat conduction, balancing the temperature of the heating body, avoiding the existence of local high-temperature heating points in the heating body, extending the life of the heating body, and preventing the water from being vaporized, thereby not generating steam jets. At the same time, the self-spinning water ring also accelerates the heat exchange between water, heats up quickly, and has small fluctuations in water temperature. The spiral heating channel 100 extends the heating path, heats quickly, and has a uniform water temperature.

[0106] In addition, since the guide ring 203 is made of a heat-conducting material and the guide ring 203 is in contact with the heating body, the heating tube 202 can conduct heat through the spiral guide ring 203, thereby increasing the contact area between the heating body and the water and increasing the water temperature. The guide tube 201 and the guide ring 203 are arranged in the heating tube 202, so that the volume of the interlayer heating channel 100 is small, thereby the heating device expands with heat and contracts with cold, and when the heating is stopped, the amount of heat overflowing water is small.

[0107] Furthermore, the ratio of the length of the heating channel 100 to the length of the heating body is set to 5-10, which can extend the heating path and improve the heating effect on the unit length of the heating tube 202. Preferably, the ratio of L1 to L2 is in the range of 6-8.

[0108] like Figure 5 and Figure 6As shown, the heating device also includes a housing 1, a water inlet unit 205 and a water outlet unit 206. The heating tube 202 is arranged in the housing 1. The water inlet unit 205 cooperates with the water inlet end of the heating channel 100, and the water outlet unit 206 cooperates with the water outlet end of the heating channel 100. The housing 1 is used for heat preservation to prevent the heat loss of the heating tube 202. The housing 1 is also used to protect the heating tube 202. The water inlet unit 205 has a water inlet 11, and the water inlet 11 is used to connect tap water or purified water. Water flows into the heating tube 202 through the water inlet 11 of the water inlet unit 205. After the water is heated by the heating tube 202, it flows out from the water outlet 12 of the water outlet unit 206. The user obtains the required hot water at the water outlet 12.

[0109] like Figure 5-Figure 7 As shown, the heating tube 202 is arranged vertically, the water inlet unit is located at the lower end of the heating tube 202, and the water outlet unit 206 is located at the upper end of the heating tube 202, forming water inlet at the lower end and water outlet at the upper end, that is, water outlet in an overflow manner. The water is heated while spirally rising in the heating channel 100. The same part of the water can contact different parts of the heating body. The water heats up quickly and evenly, and the heating channel 100 is always filled with water, preventing the heating body from having local high-temperature heating points, thereby extending the life of the heating tube 202. The terms "upper end", "lower end" and other terms describing the position here are only for explanation of the drawings, not the actual state of the product when it is used.

[0110] like Figure 5-Figure 7 As shown, the water inlet unit 205 includes a lower shell 2052, and the lower shell 2052 has a water inlet cavity. The water inlet end of the heating channel 100 is provided with a first diverter 2051, and a plurality of blades are provided on the first diverter 2051. A diverter channel is formed between adjacent blades, and the diverter channel is respectively connected with the water inlet cavity and the heating channel 100. The first diverter 2051 diverts the water through the blades and disturbs the water to form a self-spinning water ring, which prevents the water from flowing in a straight line, so that the water is disturbed before entering the heating tube 202, increases the contact opportunity between the water in different parts and the heating body, accelerates heat conduction, balances the temperature of the heating body, avoids the existence of local high-temperature heating points in the heating body, prevents the water from being vaporized, and prolongs the life of the heating body. At the same time, it also accelerates the heat exchange between the water, and the water temperature fluctuates less. The water can move along the spiral heating channel 100, prolongs the heating path, and the heating speed is fast and the water temperature is uniform.

[0111] like Figure 7 As shown, the blades of the first diverter 2051 are arranged at an angle, and the inclination direction of the blades of the first diverter 2051 is consistent with the rotation direction of the heating channel 100, forming spinning water, which increases the contact opportunities between different water and the heating body, accelerates heat conduction, and improves the water turbulence effect. At the same time, the spinning water also accelerates heat exchange between water, and the temperature rises quickly and evenly. Moreover, the spinning water has fast heat conduction, balances the temperature of the heating body, and avoids local high temperature from burning the heating body.

[0112] In another embodiment, the blades of the first diverter 2051 are tilted, and the tilting direction of the blades of the first diverter 2051 is opposite to the rotation direction of the heating channel 100 to improve the turbulence effect of water.

[0113] like Figure 5-Figure 7 As shown, the water outlet unit 206 includes an upper shell 2062, the upper shell 2062 has a water outlet cavity, and a second diverter 2061 is provided at the water outlet end of the heating channel 100. The second diverter 2061 is provided with a plurality of blades, and a diverter channel is formed between adjacent blades. The diverter channel is respectively connected to the water outlet cavity and the heating channel 100. The second diverter 2061 disturbs the heated high-temperature water so that the water can be quickly mixed and the water temperature of the water outlet 12 is balanced.

[0114] like Figure 7 As shown, the blades of the second diverter 2061 are tilted, and the tilt direction of the blades of the second diverter 2061 is opposite to the rotation direction of the heating channel 100, so that water can flow out smoothly and reduce water resistance.

[0115] In another embodiment, the blades of the second diverter 2061 are tilted, and the tilting direction of the blades of the second diverter 2061 is the same as the rotation direction of the heating channel 100, thereby improving the mixing effect of water and balancing the water temperature at the water outlet.

[0116] like Figure 8 As shown, the cross section of the heating channel 100 along the axial direction of the heating tube has a first size segment 200 and a second size segment 300. The first size segment 200 is arranged close to the heating tube 202, and the second size segment 300 is located in the middle of the cross section. The length of the first size segment 200 is greater than the length of the second size segment 300, forming a narrow structure in the middle and an open structure at the end. The open structure is arranged corresponding to the heating tube 202, and the water flow is large, so that a larger area of ​​the heating body heats the water, improving the heating efficiency. The narrow structure is far away from the heating tube 202, so that the water flow is small, so as to heat evenly.

[0117] like Figure 8As shown, the guide ring 203 is made of a heat-conducting material, and the cross-section of the heating channel 100 along the axial direction of the heating tube is a regular pattern, which includes a first straight line segment 400, a first arc segment 500, a second straight line segment 600, and a second arc segment 700 connected end to end in sequence, the first straight line segment 400 and the second straight line segment 600 are arranged oppositely, the first arc segment 500 and the second arc segment 700 are arranged oppositely, and the first arc segment 500 and the second arc segment 700 are convex in a direction close to each other. Since the guide ring 203 is made of a heat-conducting material, the heat of the heating tube 202 can be transferred to the water in the heating channel 100 through the guide ring 203, so that the first straight line segment 400, the first arc segment 500 and the second arc segment 700 can heat the water at the same time, thereby increasing the heating area and improving the heating efficiency.

[0118] In this embodiment, the guide ring 203 is forced at both ends of the heating tube 202 in the axial direction to maintain elastic potential energy. Specifically, the guide ring 203 can be compressed by the water inlet unit 205 and the water outlet unit 206 to maintain elastic potential energy of the guide ring 203, which can fix the guide ring 203 on the one hand and keep the gap between adjacent spirals fixed on the other hand to prevent the shape of the heating channel 100 from changing and affecting the heating effect. Further, the guide ring 203 can be compressed by the first diverter 2051 and the second diverter 2061 to maintain elastic potential energy of the guide ring 203.
